IMPROVEMENT IN MIDDLINGS-SEPARATORS.

Specification forming part of L'ctters Patent No. 209,182, dated October 22, 1878; application iiled January 29, 1878.

To all whom it may concern:

Be it known that I, ABRAHAM MORLEY, of the town of Cherokee, in the county of Crawford and State of Kansas, have invented a new and useful Improvement in Middlings Purifiers and Separators, of which the following is a specification, reference being had to the annexed drawing, which is made a part hereof.

Figure l is a side view of my improved machine, showing the vibrator and the machine as it appears when in use. Fig. 2 is also a side view, with the casing of the vibrator removed and parts broken away so as to show the construction. Fig. 3'is an end view.

Similar letters of reference indicate corresponding parts.

The object of this invention is to separate the branny and fuzzy particles from and to purify the middlings by subjecting them to a vibratory motion, and at the same time to the.

action of currents of air While they are passing through the machine, which machines shall be simple in construction and effective in use.

This invention consists in the combination of a vibrator, with a series of air-passages, provided with gates at their lower ends and gates or orifices at their upper ends, with a blast fan, conveying boards, chute boards, stationary dusting-boards, receiving-boards, adjustable dusting -boards, middlings-pipes, returning-boards, delivery-boards, dust-passages, exhaust-cha1nbers,and exhaust or suction fan, as hereinafter more fullydescribed.

A represents the vibrator; B, the frame of the machine; 0, the main shaft, resting in bearings on the lower part of frame B. The shaft 0 is driven by a belt passing around pulley D. E is the upper or vibrator shaft. The shaft Ei s driven by a crossed belt passing around pulley F and pulley h on main shaft 5 G, an eccentric, which works a rod passing through vibrator A, and giving motion thereto; H H, suspension-springs; I I I I,v spiral springs, four or more on each side of the machine, con necting frame B with vibrator A by means of a screw passing through each of the spiral springs I, terminating with a nut, by means of which the vibrator is also kept in a proper position. 011 the upper end of suspensionsprings H a thread is cut, upon which a nut and pass into the vibrator A by means of a flexible pipe, 1', and are discharged therefrom onto receiving-board M, whence they slide onto conveying-board P. The motionof vibrator A causes the fuzzy and branny particles to rise to the top of the middlings, from whence the said fuzzy and branny particles are blown by the current of air coming from blast-fan L through air-passage S and gate or orifice a, covered with chamois-skin, onto stationary dusting-board g. The middlings, having reached the lower end of conveying-board I, pass through orifice b, extending nearly across the lower end of said conveyin g-board P onto chute-board T, falling thence onto returning-board Q. As the middlings fall from chute'board T a current of air from air-passage S, passing through orifice or gate V,

strikes them, blowing more of the fuzzy and branny particles onto adjustable dustingboard N. The middlings pass down returning-board Q into and through middlings-pipe 0 onto receiving-board M, from whence they slide onto conveying-board P. Theirbein g constantly agitated by vibrator A brings more of the fuzzy and branny particles to the surface as the middlings pass down conveping-board P and are met by a current of air from blastfan L through airpassage S and gate or orifice a", which blows the fuzzy and branny particles onto stationary dusting-board y. The middlin gs pass down conveying-board I? through orifice 1) onto chute-board T, thence onto returning-board Q, meeting, as they fall, a current of air from air-passage S coming through orifice V, which blows the fuzzy and branny particles that become separated by falling onto adjust-able dusting-board N. The 7 middlings continue down returning-board Q fan L coming through air-passage S and gate Y Y Y by a suction or exhaust fan, K, into chambers Y Y Y by suction or exhaust fan K,

and pass through middlings-pipe 0 onto receiving-board M, thence sliding onto conveying-board P, where the agitation from vibrator A, as the middlings pass down said conveying-board P, causes more of the branny and fuzzy particles to rise to the surface, whence they are blown by a current of air from blastor orifice u onto stationary dusting-board g. The middings pass down conveying-board P through orifice 1) onto chute-board T, whence they fall onto delivery-board R,dow11 which they descend to the orifice at the bottom, and are discharged from the machine. The middlings, while falling from chute-board T to deliveryboard R, are met by another current of air from air-passage S through orifice V, and such of the branny and fuzzy particles as may have remained in the middlings are blown onto adjustable dusting-board N. The adjustable dusting-boards N N"N are regulated by a lever, a, passing through the casing of vibrator A. Immediately above the stationary dusting-boards g g g and adjustable dusting-boards N N N are dust-passages z, to permit the fuzzy and branny particles to be drawn through exhaust-chambers said exhaust or suction fan K, and expelled therefrom through its outer opening. Immediately below each receiving-board M M M" are also dust-passages r 1* r, to permit such fuzzy and branny particles as are separated from the middlin gs by their descent from the receiving-boards MM M" to conveying-boards P P P to be drawn.through into exhaustand thence, through the inner opening, into said exhaust-fan K, from which they are by it expelled through its outer opening.

The conveying-boards PP P are fastened securely to the sides of vibrator A, are three (more or less) in number, and are made with two or more grooves, extending lengthwise from the upper end to the orifice, for the discharge of the middlings near the lower end upon the chute-boards T T T.

The returning-boards Q Q Q are fastened securely to the sides of the vibrator A, are two or more in number, and are made with one groove, extending lengthwise partially or entirely through the length of the board.

The adjustable dusting-boards N N N are fastened to the end of vibrator A by pivots.

Vibrator A is connected with suction-fan K and blast-fan L by flexible pipes at a.

Having thus described myinvention, I claim as new and useful and desire to secure by Letters Patent-- 1. The combination of vibrator A, with the series of air-passages S S S, provided with gates W at their lower ends, and gates or orifices u u u and orifices V V V at their up per ends, with the blast-fan L, exhaust-chambersYY Y, and exhaust or suction fan K, substantially as herein shown and described.

2. The combination of vibrator A with conveying-boards P P P, stationary dustingboards 9 g g, receiving-boards M M M, middlings-pipes O O O, returning-boards Q Q, chute-boards T T T, adjustable dustingboards N N N, delivery-boards R R, dustpassages z and r 1' r, substantially as herein shown and described.
